Scandal of the weak

Scandal of the weak is to engage in otherwise permissible conduct that leads morally weak persons to sin. St. Paul, for example, would not eat meat that had been offered to idols because he did not want to encourage his weaker brethren to sin. He warned against "sinning in this way against our brothers and injuring their weak consciences" because then "it would be Christ against whom you sinned."[1]
